Used in masses when needed as large audiences and occasionally killed in masses. Generic Tree Friends are not colored the usual colors; they are usually shadowed, but their eyes, nose, and mouth can sometimes be seen. Most of them resemble bears, but they can resemble a variety of animals. Some can be anteaters, some can be moles or chipmunks or whatever.
In Splendid's SSSSSuper Squad, they appear as a blue gerbil/bear, a green cat, and a yellow dog. Only three are shown at a time, though they appear constantly throughout the episode.
Sometimes it is debatable whether a main character died or if it was just a generic tree friend due to similar appearances. Lumpy and Cro-Marmot are the only two main characters who can't be mistaken for Generic Tree Friends due to their appearances.
Because of his appearance, Toothy is often mistaken for a Generic Tree Friend, especially if he is in the distance or driving a vehicle when he dies.
